I pack and ship most pieces via USPS standard or priority mail. I may ship via UPS for some larger quantity orders to reduce costs. Ceramic items are fragile and are a bit heavy. This is why it costs more to ship. Shipping costs and options will be reflected during checkout. Orders are mailed in 1-5 business days after the order is placed. I do use 8”x8” and 8"x10" boxes rated up to 200 lb. and bubble wrap each mug and use recycled paper for packing to insure a safe arrival. Larger boxes may be used if needed.
